Light Source

Numerous light sources 104 may be used within system 100. In some embodiments, one or more light sources 104 may be used to facilitate release of nitric oxide from one or more photolyzable nitric oxide donors 110. In some embodiments, one or more light sources 104 may be configured to emit light of multiple wavelengths. In some embodiments, one or more light sources 104 may be configured to emit light that is selected to facilitate release of nitric oxide from one or more photolyzable nitric oxide donors 110. For example, in some embodiments, one or more light sources 104 may be configured to emit one or more wavelengths of light that are selected to facilitate release of nitric oxide from one or more identified photolyzable nitric oxide donors 110. In some embodiments, one or more light sources 104 may emit one or more wavelengths of light that are selected based on the absorption spectrum of one or more photolyzable nitric oxide donors 110. In some embodiments, one or more light sources 104 may emit one or more wavelengths of light that are selected based on decomposition of one or more photolyzable nitric oxide donors 110. For example, in some embodiments, one or more light sources 104 may be configured to emit one or more wavelengths of light that cause decomposition of one or more photolyzable nitric oxide donors 110 without causing injury to adjacent structures and/or tissues. In some embodiments, a first light source 104 may be configured to emit one or more wavelengths of light that cause a first photolyzable nitric oxide donor 110 to release nitric oxide and a second light source 104 may be configured to emit one or more wavelengths of light that cause a second photolyzable nitric oxide donor 110 to release nitric oxide. Accordingly, numerous light sources 104 may be coupled with numerous types of photolyzable nitric oxide donors 110 to provide for selective release of nitric oxide.

In some embodiments, one or more light sources 104 may include one or more quantum dots (e.g., U.S. Pat. No. 7,235,361; herein incorporated by reference). For example, in some embodiments, one or more light sources 104 may be configured to emit one or more wavelengths of light that are absorbed by one or more quantum dots. In some embodiments, one or more quantum dots may be configured to absorb light and then emit one or more wavelengths of light that cause release of nitric oxide from one or more photolyzable nitric oxide donors 110. Accordingly, in some embodiments, emission from one or more first quantum dots may be tuned to facilitate release of nitric oxide from one or more first photolyzable nitric oxide donors 110 and emission from one or more second quantum dots may be tuned to facilitate release of nitric oxide from one or more second photolyzable nitric oxide donors 110.

In some embodiments, one or more light sources 104 may be configured to be used internally to illuminate one or more regions of a user 126. A light source 104 may be configured in numerous ways. For example, in some embodiments, one or more light sources 104 may be configured for insertion into the urethra of a male and/or a female (e.g., U.S. Pat. No. 4,248,214; herein incorporated by reference). In some embodiments, one or more light sources 104 may be configured for vaginal insertion into a female. In some embodiments, one or more light sources 104 may be configured for implantation into a user 126. For example, in some embodiments, one or more light sources 104 may be configured for implantation into the genital region of a male and/or a female. For example, in some embodiments, one or more light sources 104 may be configured for implantation within the corpus cavernosa of a penis. In some embodiments, one or more light sources 104 may be configured for implantation into the scrotal sack of a male. For example, in some embodiments, one or more light sources 104 may be configured to include one or more energy sources (e.g., one or more batteries), one or more light emitters (e.g., one or more light emitting diodes), and one or more optical fibers to deliver light to a selected region of a user 126. In some embodiments, such light sources 104 may be implanted such that the energy sources and the light emitters are implanted into the scrotal sack of a male and optical fibers may be operably coupled to the one or more light emitters and implanted within the corpus cavernosa of the associated penis.

In some embodiments, one or more light sources 104 may be configured to externally illuminate a user 126. Accordingly, one or more light sources 104 may be configured in numerous ways. For example, in some embodiments, a light source 104 may be associated with a lamp, a flashlight, a wand, a ring, a glove, a sheet, a condom, a penile sleeve, and the like. In some embodiments, one or more light sources 104 may be associated with clothing.

In some embodiments, light sources 104 may be remotely controlled.

In some embodiments, one or more light sources 104 may include one or more light emitters that are coupled to one or more electromagnetic receivers 112. The one or more electromagnetic receivers 112 may be configured to couple with one or more electromagnetic transmitters 116 that produce one or more electromagnetic fields that induce an electrical current to flow in the one or more electromagnetic receivers 112 to energize the light emitters (e.g., U.S. Pat. No. 5,571,152; herein incorporated by reference). Accordingly, in some embodiments, one or more light sources 104 may be configured such that they are not directly coupled to an energy source.

A light source 104 may be configured to emit numerous types of light. In some embodiments, emitted light may be visible light. In some embodiments, emitted light may be infrared light.

In some embodiments, infrared light may be upconverted to ultraviolet light (e.g., Mendioroz et al., Optical Materials, 26:351-357 (2004). In some embodiments, one or more light sources 104 may include one or more rare-earth materials (e.g., ytterbium-erbium, ytterbium-thulium, or the like) that facilitate upconversion of energy (e.g., U.S. Pat. No. 7,088,040; herein incorporated by reference). For example, in some embodiments, one or more light sources 104 may be associated with Nd³⁺ doped KPb₂Cl₅ crystals. In some embodiments, one or more light sources 104 may be associated with thiogallates doped with rare earths, such as CaGa₂S₄:Ce³⁺ and SrGa₂S₄:Ce³⁺. In some embodiments, one or more light sources 104 may be associated with aluminates that are doped with rare earths, such as YAlO₃:Ce³⁺, YGaO₃:Ce³⁺, Y(Al,Ga)O₃:Ce³⁺, and orthosilicates M₂SiO₅:Ce³⁺ (M:Sc, Y, Sc) doped with rare earths, such as, for example, Y₂SiO₅:Ce³⁺. In some embodiments, yttrium may be replaced by scandium or lanthanum (e.g., U.S. Pat. Nos. 6,812,500 and 6,327,074; herein incorporated by reference). Numerous materials that may be used to upconvert energy have been described (e.g., U.S. Pat. Nos. 5,956,172; 5,943,160; 7,235,189; 7,215,687; herein incorporated by reference).

Control unit

Numerous types of control units 106 may be used within system 100.

In some embodiments, one or more control units 106 may be operably coupled to other components through use of one or more wireless connections, one or more hardwired connections, or substantially any combination thereof. Control units 106 may be configured in numerous ways. For example, in some embodiments, a control unit 106 may be configured as an on/off switch. Accordingly, in some embodiments, a control unit 106 may be configured to turn a light source 104 on and/or off. In some embodiments, a control unit 106 may be configured to control the emission of light from one or more light sources 104. For example, in some embodiments, one or more control units 106 may regulate the intensity of light emitted from one or more light sources 104, the duration of light emitted from one or more light sources 104, the frequency of light emitted from one or more light sources 104, wavelengths of light emitted from one or more light sources 104, or substantially any combination thereof. In some embodiments, one or more control units 106 may be configured to receive one or more signals 118 from one or more remote sensors 120. Accordingly, in some embodiments, one or more control units 106 may be configured to control one or more light sources 104 in response to one or more signals 11 8 received from one or more remote sensors 120. For example, in some embodiments, one or more remote sensors 120 may sense a low concentration of nitric oxide in one or more tissues and send one or more signals 118 to one or more control units 106. The one or more control units 106 may then turn one or more light sources 104 on to facilitate release of nitric oxide from one or more photolyzable nitric oxide donors 110. Accordingly, in some embodiments, one or more remote sensors 120 may sense a high concentration of nitric oxide in one or more tissues and send one or more signals 118 to one or more control units 106. The one or more control units 106 may then turn one or more light sources 104 off to end release of nitric oxide from one or more photolyzable nitric oxide donors 110. In some embodiments, one or more control units 106 may be programmed to control one or more light sources 104. For example, in some embodiments, one or more control units 106 may be programmed to turn one or more light sources 104 on for a predetermined amount of time and then turn off. Accordingly, in some embodiments, one or more control units 106 may be preprogrammed. In some embodiments, one or more control units 106 may be dynamically programmed. For example, in some embodiments, one or more management units 122 may receive one or more signals 118 from one or more remote sensors 120 and program one or more control units 106 in response to the one or more signals 118 received from the one or more remote sensors 120. In some embodiments, one or more control units 106 may include one or more receivers that are able to receive one or more signals 118, one or more information packets, or substantially any combination thereof. Control units 106 may be configured in numerous ways. For example, in some embodiments, one or more control units 106 may be operably coupled to one or more light sources 104 that include numerous light emitting diodes that emit light of different wavelengths. Accordingly, in some embodiments, one or more control units 106 may control the wavelengths of light emitted by the one or more light sources 104 by controlling the operation of light emitting diodes that emit light of the selected wavelength. Accordingly, control units 106 may be configured in numerous ways and utilize numerous types of mechanisms.

However, it should be understood that the modules may execute operations in a number of other environments and contexts, and/or modified versions of FIG. 1. Also, although the various modules are presented in the sequence(s) illustrated, it should be understood that the various modules may be configured in numerous orientations.

The embodiment 200 may include module 210 that includes one or more light sources that are specifically configured to emit light that facilitates release of nitric oxide from one or more photolyzable nitric oxide donors. In some embodiments, device 102 may include one or more light sources 104 that are specifically configured to emit light that facilitates release of nitric oxide from one or more photolyzable nitric oxide donors 110. A light source 104 may be configured in numerous ways. For example, in some embodiments, a light source 104 may include a chemiluminescent light source 104.

For example, in some embodiments, one or more light sources 104 may be configured to emit one or more wavelengths of light that facilitate photodecomposition of one or more photolyzable nitric oxide donors 110. In some embodiments, one or more light sources 104 may be configured such they do not emit one or more wavelengths of light that do not facilitate photodecomposition of one or more photolyzable nitric oxide donors 110. Accordingly, in some embodiments, one or more light sources 104 may be configured to emit light that is matched to one or more photolyzable nitric oxide donors 110 and causes photodecomposition of the one or more photolyzable nitric oxide donors 110. In some embodiments, one or more light sources 104 may be configured such that they do not emit light that cross-links biological structures (e.g., proteins) or that causes the formation of DNA adducts. Accordingly, in some embodiments, one or more light sources 104 may be configured to emit light that photolyzes one or more photolyzable nitric oxide donors 110 with reduced damage to surrounding tissue. For example, in some embodiments, one or more light sources 104 may be configured to emit visible light (λ=550 nm) to facilitate homolytic decomposition of S-nitrosoglutathione to generate nitric oxide (e.g., Singh et al., FEBS Letters, 360:47-51 (1995)). In some embodiments, ultraviolet light may be used to facilitate release of nitric oxide from one or more photolyzable nitric oxide donors 110. For example, in some embodiments, one or more light sources 104 may be configured to emit ultraviolet light (λ=355 nm) to release nitric oxide from S-nitrosothiols (e.g., Rotta et al., Braz. J. Med. Biol. Res., 36:587-594 (2003)). In some embodiments, one or more light sources 104 may be configured to emit light over a broad range of wavelengths that will facilitate release of nitric oxide from one or more photolyzable nitric oxide donors 110.

Accordingly, in some embodiments, one or more light emitters may be configured to emit visible light that facilitates release of nitric oxide and to not emit ultraviolet light which may cause damage to tissue associated with a user associated with the released nitric oxide. For example, in some embodiments, one or more light sources 104 may be configured to emit visible light (λ=550 nm) to facilitate homolytic decomposition of S-nitrosoglutathione to generate nitric oxide but not emit ultraviolet light (e.g., Singh et al., FEBS Letters, 360:47-51 (1995)). In some embodiments, ultraviolet light may be used to facilitate release of nitric oxide from one or more photolyzable nitric oxide donors 110. For example, in some embodiments, one or more light sources 104 may be configured to emit ultraviolet light (λ=355 nm) to release nitric oxide from S-nitrosothiols (e.g., Rotta et al., Braz. J. Med. Biol. Res., 36:587-594 (2003)). In some embodiments, one or more light sources 104 may be configured to emit light over a broad range of wavelengths that will facilitate release of nitric oxide from one or more photolyzable nitric oxide donors 110. For example, in some embodiments, O²-benzyl substituted diazeniumdiolates, O²-napthylmethyl substituted diazeniumdiolates, and/or O²-napththylallyl substituted diazeniumdiolates may be photolyzed by light over a broad range of wavelengths (λ=254 nm to λ=700 nm) (e.g., U.S. Pat. No. 7,122,529). Accordingly, in some embodiments, one or more light emitters may be configured to emit light that is paired with one or more photolyzable nitric oxide donors 110 to facilitate release of nitric oxide from the one or more photolyzable nitric oxide donors 110.

In some embodiments, a light source 104 may be configured to have a power source that may be implanted into the lower abdomen of a male and a light emitter that is configured for placement in the corpus cavernosa of the penis. In some embodiments, such a light source 104 may be used to facilitate release of nitric oxide from one or more photolyzable nitric oxide donors 110 within the genital region. Accordingly, in some embodiments, such an implanted light source 104 may be configured for use in association with treatment of erectile dysfunction. In some embodiments, one or more light sources 104 may be configured for implantation in association with the vasculature of a user 126. For example, in some embodiments, one or more light sources 104 may be configured for implantation in association with an implanted vascular stent. Accordingly, in some embodiments, one or more light sources 104 may be configured to facilitate release of nitric oxide from one or more photolyzable nitric oxide donors 110 in the region of the vasculator that is associated with the implanted stent. Light sources 104 may be configured for implantation in numerous ways.

In some embodiments, one or more light sources 104 may include one or more light sources 104 that are configured to emit one or more wavelengths of light that are between 254 nm and 700 nm. For example, in some embodiments, a light source 104 may be configured to emit ultraviolet light (λ=350 nm to 360 nm) to release nitric oxide from S-nitrosothiols and not emit other wavelengths of light (e.g., about 254 nm to about 349 nm and about 361 nm to about 700 nm). Accordingly, the emission of light from one or more light sources 104 may be coupled to wavelengths of light that facilitate release of nitric oxide from one or more photolyzable nitric oxide donors 110. In some embodiments, one or more light sources 104 may be configured such that they do not emit one or more wavelengths of light that do not facilitate release of nitric oxide from one or more photolyzable nitric oxide donors 110.

With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations are not expressly set forth herein for sake of clarity.

While particular aspects of the present subject matter described herein have been shown and described, it will be apparent to those skilled in the art that, based upon the teachings herein, changes and modifications may be made without departing from the subject matter described herein and its broader aspects and, therefore, the appended claims are to encompass within their scope all such changes and modifications as are within the true spirit and scope of the subject matter described herein. Furthermore, it is to be understood that the invention is defined by the appended claims. It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”

Those having skill in the art will recognize that the state of the art has progressed to the point where there is little distinction left between hardware and software implementations of aspects of systems; the use of hardware or software is generally (but not always, in that in certain contexts the choice between hardware and software can become significant) a design choice representing cost vs. efficiency tradeoffs. Those having skill in the art will appreciate that there are various vehicles by which processes and/or systems and/or other technologies described herein can be effected (e.g., hardware, software, and/or firmware), and that the preferred vehicle will vary with the context in which the processes and/or systems and/or other technologies are deployed. For example, if an implementer determines that speed and accuracy are paramount, the implementer may opt for a mainly hardware and/or firmware vehicle; alternatively, if flexibility is paramount, the implementer may opt for a mainly software implementation; or, yet again alternatively, the implementer may opt for some combination of hardware, software, and/or firmware. Hence, there are several possible vehicles by which the processes and/or devices and/or other technologies described herein may be effected, none of which is inherently superior to the other in that any vehicle to be utilized is a choice dependent upon the context in which the vehicle will be deployed and the specific concerns (e.g., speed, flexibility, or predictability) of the implementer, any of which may vary. Those skilled in the art will recognize that optical aspects of implementations will typically employ optically-oriented hardware, software, and/or firmware.

The foregoing detailed description has set forth various embodiments of the devices and/or processes via the use of block diagrams, flowcharts, and/or examples. Insofar as such block diagrams, flowcharts, and/or examples contain one or more functions and/or operations, it will be understood by those within the art that each function and/or operation within such block diagrams, flowcharts, or examples can be implemented, individually and/or collectively, by a wide range of hardware, software, firmware, or virtually any combination thereof.

Those skilled in the art will recognize that electro-mechanical as used herein is not necessarily limited to a system that has both electrical and mechanical actuation except as context may dictate otherwise.

In a general sense, those skilled in the art will recognize that the various aspects described herein which can be implemented, individually and/or collectively, by a wide range of hardware, software, firmware, or any combination thereof can be viewed as being composed of various types of “electrical circuitry.” Consequently, as used herein “electrical circuitry” includes, but is not limited to, electrical circuitry having at least one discrete electrical circuit, electrical circuitry having at least one integrated circuit, electrical circuitry having at least one application specific integrated circuit, electrical circuitry forming a general purpose computing device configured by a computer program (e.g., a general purpose computer configured by a computer program which at least partially carries out processes and/or devices described herein, or a microprocessor configured by a computer program which at least partially carries out processes and/or devices described herein), electrical circuitry forming a memory device (e.g., forms of random access memory), and/or electrical circuitry forming a communications device (e.g., a modem, communications switch, or optical-electrical equipment).
